Getting started with the X-NUCLEO-IHM05A1 L6208-based
bipolar stepper motor driver expansion board for STM32 Nucleo
Introduction
The X-NUCLEO-IHM05A1 is a bipolar stepper motor driver expansion board based on the L6208 DMOS
driver for bipolar stepper motors.
It provides an affordable and easy-to-use solution for driving bipolar stepper motors in your STM32
Nucleo project.
The X-NUCLEO-IHM05A1 is compatible with the Arduino UNO R3 connector, and supports the addition
of other STM32 expansion boards with a single STM32 Nucleo board. The user can also mount the ST
Morpho connector.

1 Getting started
The X-NUCLEO-IHM05A1 expansion board for STM32 Nucleo is a bipolar stepper motor
driver covering a wide range of applications. In particular, the maximum ratings of the
board are the following:
Power stage supply voltage (VS) from 8 V to 50 V
Motor phase current up to 2.8 A r.m.s.
Follow this sequence to start your project with the board:
1. Check the jumper position based on your configuration (see Section 2: "Hardware
description and configuration")
2. Connect the X-NUCLEO-IHM05A1 with the STM32 Nucleo board through Arduino
UNO R3
3. Supply the board through the input 6 (VS) and 5 (ground) of the connector CN1
4. Develop your application using the examples provided with the firmware library, X-
CUBE-SPN5
Further support material is available on the L6208 and the STM32 Nucleo web pages on
www.st.com.

2.1 Board setup
The X-NUCLEO-IHM05A1 STM32 expansion board is designed to operate with all STM32
Nucleo boards thanks to its Arduino UNO R3 connector.
Some STM32 Nucleo boards generate the VREFA reference using pin 4 of CN9 (pin 31 of
CN10), while other boards use pin 4 of CN5 (pin 15 of CN10). By default, both pins are
connected to the VREFA pin of the motor driver, so the board is ready to use.
If the driving STM32 Nucleo board uses pin 4 of CN9 (pin 31 of CN10) for reference
generation, pin 4 of CN5 (pin 15 of CN10) can be left at user disposal by removing the 0-
ohm R15 resistor.
